Decode Base64

Base64 shows up in email attachments, data URIs, API tokens and debug dumps. Decoding it restores the original bytes or text instantly.

  1. Paste the Base64 string (whitespace is tolerated).
  2. Choose the alphabet if the source uses URL-safe characters.
  3. Inspect the decoded output, or download it when it is binary.
